Preformed tune up on package unit, since last repair unit has been working well the homeowner said. I looked everything over and it seems to be in good condition for the age. There was a couple items that we recommended, one thing is we should do an indoor coil clean as it’s getting dirty. Dirt does make it past filters and it should be cleaned periodically . The other item is the drain line has no safety switch or drain clean out. If the drain backs up this prevents water coming in home. It’s very common to have these on units as most new units have them installed from the start. Other wise everything looks pretty good. Homeowner is 98 and normally goes over stuff like this with her daughter. I told her it’s no issue at all and if they decide to go with my recommendations to just give us a call and we will get it done for her. Unit running at departure.
